srsca'rzon forming 5m of Letters Patent No; 049,390, dated May a, 1900. Applieation'flled N e r 1, 1899! Serial No. 798,490. (No model-l To all wltom it may concern.-

lie it known that I, PAUL O. E. BOUDREAUX, residing at Thorlot, in the parish of Terre lionneandState of Louisiana, have made cer'-' 5 tain new and useful Improvements in Engiines, of which the following is a specificat on.

My invention is an improvement in steam and air engines; and it consists in certain novel constructions and combinations of parts, as will be hereinafter described, and pointed out in the claims. A

In the drawings, Figure 1 is a side view of an engine embodying my invention and com nected and adapted for use as a com pressedair engine. Fig. 2 is adetail section on about line 2 2 of Fig. 1. Fig. 3 isa detailsection on about line 3 3 of Fig. 2,-and Fig. 4 is 'a detail view of the pump for recharging the storagecylinder. r

In the construction shown in Fig. 1 the several parts are constructed, adapted, and arranged for operationas a compressed-air engine. in the said construction I employa storage-cylinder A, which may correspond to the steam-boiler when the invention is embodied in a steam-engine; suitable heating meansbeingeinpioyed. ThiscylinderAisprovided with a safety-valve A, a storage-chamher A which is composed of indie-rubber or other suitable elastic material, and the feedfiipeB which leads from the boiler to a pipe having a throttle l3 and connected at the pipes Bi, having throttles B The pipes B lead to the valve-casings C and D, in which operate the valves C, which control the passage of the air, steam, or other motive force to the cylinders for operating the wheels E and F. ()ne oi these sets of cylinders is shown in Fig. 3, and it includes cylinders G and ill, arranged alongside'each other and having feed-ports G and H, communicating with the valve-chest, and exhaust-ports G and H. Pistons G 5- cylinders G and H and carry the stems G and li which operate upon the wheels E and F, recently described. The pistons G H an their stems G ll are forcedoutward by the steam or air until the pistonspass their "will be understood from springs G? and *II'will QPGI'P Fig. 3, when the turned by the springs. The Bassage of steam and ii operate in the" ate to return the pistons to the startingint,

as shown by the piston II" in Fig. n the operation of this construction it will be seen the valve admits steam alternately through the ports G and H, .and thus the pistons G and H will be reciprccated alternately, being forced outward by the air or steam and re or air to the valve-casings and D may be 60 regulated and controlled by the throttlevalves before described.

' The pistons operate upon their wheels E or F. Each of these wheels is composed of sec' tions E F and E and F, as will be understood from Figs. 1 and 2, the teeth of the sections alternating with each other and beingarranged in the path of the valve-stems Gand ll, so the alternatereciprocating movement of the stems Gand H will tend to rotate the shaft 1, to which the wheel E is secured.

The wheel F, like the wheel E, is secured to the shaft I i but its teeth face in the opposite direction-from those of the wheel E, the purpose being to provide a reversing mechanism, so the shaft I can be turned in one direction by operating upon the wheel E and in-ihe opposite direction by operating upon the wheel F, it being understood that the cylinders for the pistons which operate upon the wheel F are arranged at an'sngle to those which opcrate uponthe wheel E. This is indicated in. Fig. 2 of the drawings.

The shaft I is provided with a cam-groove J, in which operates one end of a lever .l', which is pivoted centrally at J and has its other end connected by a link 3 with a lever J", which is connected with the valves in caslegs 0 or D. Thus, as shown in Fig. 1, the valve in casing O is connected by its link it with the lever J, so the steam or air will be supplied to the casing C, the casing D being detached. When no adjusted, the piston-rods will act upon the wheel E to turn the shaft in ,one direction. To turn the shaft in the other direction the link J should be detached and the link J of thevalve in the casing D be coupled with the lever J when the steam or-air will be fed to the casing D and the wheel F- will be operated torturn the shaft I in the other direction, as desired.

r In the use of the invention as a com pressednewing the pressure therein when desired.

In the use of my invention as a steam-en gine the parts K, L L, M M, and M and M may be disconnected or omitted, and the part A? may likewise be omitted. 4

Having thus described myinvention, what I-claim as new,and desire to secure by Letters Patent, is-

1. An apparatus substantially as described comprising the sh aft having-a wheel provided with sets of alternating teeth, the cylinders corresponding to said alternating teeth, the pistons operating in said cylinders and having stems o'r rods engaging with the alternating teeth, and valve devices controlling the admission of the operating medium to the said cylinders substantially as set forth.

2. The combination in an apparatus substantially as described of the wheel having alternating teeth, the cylinders corresponding to the alternating teeth and having inlet and exhaust ports, the pistons operating in said cylinders and having stems or rods engaging the alternating teeth, and the springs for returning the pistons substantially as set forth'J p ,4

3. In an apparatus substantially as described" thiacb'mbination of the shaft, the wheels thereon having alternating sets of teeth, the two pair of cylinders overlying the shaft and arranged at reverse inclines and practically fixed in such reversely-inclined relation, the ,pistons operating in said cylinders and ha ng stems or rods engaging the teeth ofthei respective wheels, and valve devices substantially as set forth. I 4. The combination in an apparatus substantially as described of the wheels E and F having alternating teeth and the teeth of the wheel E being reversed with respect to those of the wheel F, the cylinders arranged in pairs, one pair corresponding to each wheel,

the pistons in said cylinders and having stems 9r rods engaging the teeth of the wheel, the valve-gear, the valves controlling the passage of power to the two pairs of cylinders, and detachable connections between such valves and the valve-gear substantially as ,set forth.

5. In an apparatus substantially as described the combination of the v engine, the

storage-cylinder, vpipe connections for feed ing the engine from the cylinder and an elastic storage-chamber connected with the cylinder, and a pump arranged for operation by the engine and adapted to recharge the cylinder substantially as set forth.

6. In anapparatus substantially as' de= scribed the combination with the shaft I having a cam-groove J, the wheels E and F-secured to said shaft, the cylinders, the pistons in said cylinders and having the alternatelyreciprocating rods or; stems, the valves, and the valve-gear including a lever J, a link J a lever J and links connected with the valves and-adapted -for detachable connection with the lever J PAUL o.
